SUPPORT FOR SPINNING-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 408,582, dated August 6, 1889.

Application filed April 16, 1889. Serial No. 307,447. (No model.)

To all whom, it may concern.-

Be it known that I, CHARLES H. CHAPMAN, of Groton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Supports for Spinning-Spindles, of which the following is a specification.

My invention relates to spinning-spindles and supports therefor generally, and particularly to that class of spindles and spindle-supports which enable the spindle to find its true center or axis of rotation, and therefore to be accommodated to its load.

It is the object of my invention to provide such improvements in the class of spindles mentioned as will overcome defects and objections existing in present structures, and at the same time provide means whereby the spindle and spindle-bearings may be readily and efficiently lubricated, all as hereinafter described, and pointed out in the appended claims.

Of the drawings hereunto annexed and forming a part of this specification, Figure 1 is a sectional view (showing a portion of the spindle in elevation) of the sleeve-whirl, bolster-rail, bolster-case, spindle-bearings, and lubricating-cups. Fig. 2 is a side view of the shell for supporting the bolster-bearing and step and the support for said shell. Fig. 2 is a top plan View of Fig. 2. Fig. 3 is a front View of the shell and bolster support. Fig. 3 is a top plan view of Fig. 3. Fig. 4 is a side view of the bolster-bearing. Fig. 4 is a top plan View of Fig. 4.. Fig. 5 is a side view of a modified form of a bolster and shell support. Fig. 6 is a top plan View of Fig. 5. Fig. 7 is a top plan view of the step. Fig. 8 is a side elevation of the nut for securing the bolster-case to the rail, showing an oil-cup in position on said nut. Fig. 9 is a top plan view of the oil-cup adapted to beapplied to the bolster-case-securing nut. Fig. 10 is a cover or rim adapted to be arranged on the nut above the oil-cup secured thereto. Fig. 11 is a side view of Fig; 10.

The same letters of reference designate the same parts or features, as the case may be, in all of the views. v

In carrying out my invention I provide a suitable bolster-case a, preferably provided on its upper end with an oil-cu p Z), and secure said bolster-case to the rail 0 by means of a suitable nut d.

edesignates a shell arranged in the bolstercase and sustained therein by means of an elastic support f, extending up from a ring or thimble c, secured in the bolster-case a. h designates the bolster-bearing, arranged in the upper portion of the shell 6 and secured thereto and therein by means of a rivet 'i, which passes through the bolster-bearing h, shell e, and elastic support f, as shown in Fig. 1. The point at which the elastic support f, the shell, and the bolster are secured together is desirably (though not necessarily) central of the sleeve-whirlj, so as that such point shall be substantially on a line with the bandpull. Instead of employing the rivet t to secure the elastic support f to,the other parts, I may use solder or other suitable uniting means.

The shell 6 extends down through the open bolster-case a, the bore in the latter being suificiently large to allow of limited lateral movement of the shell without contact with the interior of the bolster-case.

k designates the step secured in the lower end of the shell, and in or upon which the foot of the spindle s rests, said spindle extending from the step up through the shell and through the bolster-bearing, and running in contact with the latter, but not touching the former.

I have herein shown the interior of the upper portion of the shell 6 as provided with an oifset Z, and the exterior of the upper end of the bolster-bearing as provided with a shoulder m, arranged to rest on theoffset Z. I have also shown a practically rigid guard 12, extending around the elastic support f from the thimble g to or near to the shoulder formed on the exterior of the shell e at the offset point Z, which rigid guard tends to keep the spindle and shell in an upright position and prevent the band-pull from unduly deflecting the spindle or drawing it out of center with respect to the ring, it being understood that the band-pull is in a direction toward the rigid guard 31, as indicated by the arrow in Fig. 2. These several parts and features may, however, be modified or entirely dispensed with without departing from the 11ature or spirit of my invention. Concerning changes that may be made in the form of the devices specified, it may be mentioned, for example, that the shell and bolster-support may be constructed as shown in Figs. and 6, wherein the thimble g is represented as provided with a plurality of elastic supports or spring-tongues f f and a rigid guard f Said elastic supports and rigid guard extend up to and on practically opposite sides around the bolster-bearing, one of said elastic supports being riveted or soldered or otherwise secured to the bolster-bearing, as before described, rigid guard f subserving the functions accomplished by the rigid guard n shown in Figs. 2 and 3. With this construction the shell carrying the bolster-bearing and step, being sustained in position by the elastic support f or f, is permitted to yield to accommodate the spindle to its load. At the same time, the tension of the elastic support f bein g in the direction of the arrow, Fig. 2, and the pull of the band being in the same direction, the shell is kept from undue deflection from a vertical 7 line by the rigid guard 42, which construction and arrangements of parts also tend to maintain the spindle in vertical position and to all intents and purposes in the center of the ring. 7

0 designates an oil-cup, which maybe spun up from a blank of sheet metal and sprung upon the lower end of the nut (1, so that its edges will snap or catch into notches 1) formed in cars q of said nut, by which an open-top cup is provided adapted to receive oil and supply the same to the step and other bearings of the spindle through the aperture n in the shell.

0* designates a cover or rim adapted to be supported on the nut (i above the cup 0, to keep dust and dirt from settling or falling into cup, said rim being partially cut away, as at s s, so that it may be arranged over the ears (1 and closely down on the top of the cup. At the same time itis so constructed and arranged as to be adapted to be slipped upon the neck of the nut to allow of oil being supplied to the cup.

The shell 6 may be extended above the bolster-bearing 71, so as to form an oil-cup thereabove, as at t. A hole u is formed in the bolster-casing a, leading from the oil-cup l) to the interior of the casing outside of the shell 6, so that the oil supplied to the spindle from the cup 0 through the aperture n formed in the lower end of the shell 0, and by the rot-ation of the spindle carried up to the bolsterbearing, the latter being rifled on its interior surface, as is common, and filling and flowing over the cup i, may drip down into cup I) and flow back through the hole a to the cup 0, to be again supplied to the spindle. A sleeve or apron w is connected with the whirl and extends down into the oil-cup b, to conduct the overflowing oil from the top of the spindle-support into the oil-cup b. 00 designates a cover to oil-cup b to keep dust and dirt out of oil-cup b.

y designates a stop-pin of common construction, the office of which is to prevent the spindle from being pulled out of its bearing in dofiing the bobbin.

Having thus explained the nature and purposes of my invention and described some of the ways of eonstructin g and manners of using the same, I declare that what I claim is- 1. A spindle and bolster-case, combined with a shell arranged in said bolster-case, a stepbearing supported by said shell, a bolsterbearing arranged in said shell, and an elastic support attached to the bolster-ease and secured to the shell and bolster-bearing, as set forth.

2. A spindle and its sleeve-whirl and a bolster-case provided with a shell having a bolster and step bearing, and an elastic support attached to the bolster-ease and secured to the bolster-bearing and shell at a point substantially on a line centrally of the whirl, as set forth.

. 3. A spindle and its sleeve-whirl and a bolster-case provided with a shell having a stepbearing in its lower end and a bolster-bearin g in its upper end, and a rigid guard to prevent undue deflection of the shell and spindle attached to the bolster-case, and having an elastic support secured to the bolster-bearing and shell, as set forth.

4. A spindle and its sleeve-whirl and a bolster-ease, combined with a bolster and step support, a rigid guard, and an elastic support for the bolster and step support, as set forth.

5. A support for the bolsters of spinningspindles, consisting of a rigid guard and an elastic support, as set forth.

6. The combination, with the open bolstercase and a bolster and step supporting shell suspended therein and extending therethrough, of the nut d, provided with ears q, and an open sheet-metal oil-cup adapted to be sprung upon and held by said ears, as set forth.

7. The combination, with the open bolstercase, of the nut for securing the bolster-case to the rail, an open sheet-metal oil-cup adapted to be sprung upon and held by said nut, and the covering-rim arranged upon said nut over said cup, as set .forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 10th day of April, A. I). 1889.
